PLEASE HELP! I can't find a title of a movie, it's driving me crazy

Please help me, I once watch a movie and I can't find it anymore... It's a love story between two teenagers. The boy comes to a new town (small one, desert(fish) type) with his mother. There car broke and a man offers them to live in the backyard trailer. That man has a daughter, she hides a part of her face because she was burnt or something like that. the boy is sick (cancer I think). They fall in love, he dies at the end in front of the ocean.Thank you so much if you can find it!

I've tried everything, every research and web site and I can't find it... It's like if I invented it in my head and it's killing me!!!
